Founder-built systems and tools
Side Projects
Weekend builds, experiments, and things I tinker with. Swipe through.
Chris Zemmel
I've been in crypto for 9 years, and I've spent them building whatever the problem actually needed: AI systems, security tooling, health-tech infrastructure, and blockchain rails, not just one lane. Right now I'm Co-Founder and CTO at OneHealth, building the event-sourced canonical record behind a health navigator, and raising a pre-seed to take it further. Alongside that I built Panoptes, an AI security-review pipeline that's reviewed 160+ targets across 29 ecosystems and flagged real consensus-verification gaps in a live cross-chain bridge that's moved over $100M. I tend to ship solo and end to end: Enjin Governance runs on roughly 330 passing tests and went open-source the same day its funding proposal passed, and nimimo's cryptographic core is open under AGPL-3.0. If any of that maps to what you're building, whether that's an engineering hire, an audit, an investment, or just a conversation, I'd like to hear from you.
Five pillars, zero filler
AI & Autonomous Systems
Multi-agent systems that decide, not just autocomplete.
Multi-Agent Orchestration
- ▹Multi-agent AI councils run by a deterministic orchestrator: typed contracts, domain routing, conflict resolution
- ▹Model-agnostic provider layer, swappable the day a stronger model ships
- ▹Reproducible inference: deterministic policy gates wrapped around probabilistic agents
Applied LLM Engineering
- ▹Use-case-specific prompt engineering, semantic pipelines, and structured extraction
- ▹Multimodal ingestion: documents, images, and free text normalised into typed data
- ▹Production AI surfaces: chatbots, analyzers, and generative document tooling
Security, Privacy & Cryptography
Built like it will be attacked, because it is.
Autonomous Security Review
- ▹Invariant-directed AI audit pipeline reviewing critical code invariant by invariant
- ▹One engine across EVM, Solana, Move, Cosmos, Substrate, Bitcoin, ZK circuits, and web2 access-control
- ▹Detection-only and human-triaged against 100+ vulnerability classes: finds and reports, never exploits
Applied Cryptography & Access
- ▹Non-custodial key management and device-bound encryption, kept fully client-side
- ▹SIWE-style signature sign-in, rotating httpOnly sessions, and Row Level Security
- ▹Hard separation of access, identity, ownership, and recovery, with open-core crypto under AGPL
Privacy & Compliance
- ▹Identity stripped at ingestion, before any model sees the data, and privacy regression-gated on every change
- ▹HIPAA / GDPR-style posture: encryption in transit and at rest, append-only audit logs, zero-retention model APIs
- ▹Data residency as a deploy choice, with a BAA / DPA posture across every processor
Blockchain & Crypto Infrastructure
9 years in crypto, shipping the rails, not the hype.
Industry Experience
- ▹9 years of crypto experience
- ▹Built and ran blockchain platforms end to end: product, QA, support, DevRel, and marketing
On-Chain Governance
- ▹Production Enjin OpenGov client: conviction voting, treasury proposals, live RPC + archive reads
- ▹EGOV1 on-chain metadata standard with content-addressed proposal backlinks
- ▹Multi-wallet: WalletConnect v2 + Polkadot.js / Talisman / SubWallet / PolkaGate
Non-Custodial Rails
- ▹Single-link receive across BTC / ETH / SOL / USDC, keys on-device
- ▹Device-bound key encryption, recovery flows, and open-core crypto under AGPL
- ▹Token gating, credit systems, and usage metering
Systems & Platform Architecture
Event-sourced foundations that scale and never lie about history.
Event-Sourced Foundations
- ▹Append-only, immutable event logs as the single source of truth
- ▹Canonical data layers that normalise messy vendor payloads
- ▹State as a fold over history, answering "what changed and why" at any point
Full-Stack & Distributed
- ▹TypeScript / Next.js product surface; Python for data and ML services
- ▹Small, independent, containerised services that ship and scale on their own
- ▹REST, Webhooks, GraphQL, real-time indexing, and event-driven pipelines
Reliability at Scale
- ▹Idempotent real-time transaction handling, retries, and batch processing
- ▹Rate-limit-aware CDN caching with graceful fallbacks
- ▹150,000+ on-chain operations handled in production
Human-in-the-Loop
- ▹Review and approval gates before any autonomous action
- ▹Provenance-tagged data with traceable, causally-linked outcomes
Product, Automation & Execution
One person, the whole stack, from blank repo to shipped product.
0 → 1 Founder MVPs
- ▹Rapid architecture from idea to execution, shipped solo
- ▹Systems that "just work": elegant, focused, minimal config
Automation & Data Engineering
- ▹Internal tools, operational dashboards, financial projections, and reporting
- ▹Transaction parsing and tagging into structured pipelines; cost forecasting from history
- ▹Custom technical indicators, token-based access, and tiered pricing mechanics
Interface & Craft
- ▹Interfaces that adapt to user state and input type, with empathy-driven tone
- ▹Strong eye for minimalism, motion, and clean UI copy
One-Man Workforce
- ▹Full ownership from ideation to deployment, across every discipline
- ▹DevRel and community to product, QA, and marketing, whatever the role needs
